The Government Bridge, also known as the Arsenal Bridge, spans the Mississippi River between Rock Island, Illinois, and Davenport, Iowa. Built in 1896, the bridge has two levels: the upper deck serves the Iowa Interstate Railroad, while the lower deck carries vehicle traffic and has lanes on each side for pedestrians and cyclists. It features a swing section to allow river navigation. The current bridge is the fourth at this location; the first, built in 1856, was the first railroad bridge across the Mississippi. Subsequent bridges were built after damage from collisions, ice storms, and tornadoes.
